Maybe its a dumb question but I know little about drones and how to view their in flight video on a smart phone or tablet. As I read it they transmit the video by wifi. So I'm wondering does this use up some of my monthly quota of 10 gig high speed? We have good wireless internet but are capped at 10 gig per month out here in the sticks. While it is good and fast up to that point, after hitting the 10 gig limit we are throttled back to just medium fast. 
I don't have a smart phone or a tablet, or even a drone yet. But I'm considering the options and need to ask a few dumb questions.
